Set Number | Leapwork Docs

The Set number building block defines a number value, typically used as a constant that you pass into other building blocks (for example Calculate).

Note: The screenshot on this page uses the Elegance Design, introduced in 2025.3. If you are using an earlier version, your layout may look different.

Quick-start

Drag Set number onto the canvas.
Enter Number value, then connect the value to the next block that needs a numeric input.
Run the flow when it’s ready.

Building block parameters

Parameters

Block header: Shows the current title of the block. You can rename it by double-clicking the header text and typing a new title. This block has no green input or output connectors in the header because it is not explicitly executed. Instead, it sets a number value for other blocks.
Number value: The numeric value to be used by other building blocks.
